[c-nsp] Best Routing Protocol for Scenario

[Paul Stewart]

Sure, checkout

http://www.nexicom.net/~turbo/customernetwork.vsd 

It's in Visio...

We want the voice traffic to take the T1's and the data traffic to take the
bridged ADSL ethernet connections.... we have this working now using static
routing but I want dynamic routing in place - trying to identify best
dynamic routing protocol to use....

Someone suggested EIGRP which makes some sense...;)

Thanks,

Paul

Can you draw a jpeg that shows the layout?

That's a lot easier than trying to draw it from email.
